Abstract
Formal verification has been successfully applied to provide strong correctness guarantees of software systems, but its application to large code bases remains an open challenge. The technique of component-based software development, traditionally employed for engineering benefit, also aids reasoning about such systems. While there exist compositional verification techniques that leverage the separation implied by a component system architecture, they implicitly rely on the component platform correctly implementing the isolation and composition semantics they assume. Any property proven using these techniques is vulnerable to being invalidated by a bug in the code of the platform itself. In this paper, we show how this assumption can be eliminated by automatically generating machine-checked proofs of the correctness of a component platform’s generated Remote Procedure Call (RPC) code. We demonstrate how these generated proofs can be composed with hand-written proofs to yield a system-level property with equivalent assurance to an entirely hand-written proof. This technique forms the basis of a scalable approach to formal verification of large software systems.
